'Appiication Afiled october 27, 1926-. Serial No. 144,428.

lThe object of my present invention,

broadly speaking, is to vprovide a-combina a. con'iparative- Y ployed inconnection lwith framing pictures' or the like to provide-means fortrimming off theedges of the backing or sealing paper which haspreviously-been pasted overgthe back of the frame, for forming holes vinY the frame for starting screw-eyes, and f oi` turn-,

ing the screw-eyes securely into tlieirpfinal position in said holes. Y

Other lobjects and particular Y advantages of my invention will suggestthemselves in, the course of the following description, and

that which is vnew will be broughtl outiii the appended claim. l y

rllie preferred means for carrying out the principles ofmy invention ina practical, ef-A licient, and mechanically correct manner, is shown inth'e accompanying drawings, -in whichFig. 1 is a perspective `view. ofmy inventioin'as it would appear in actual practice as performing one ofits operations;

Sin'iilar indices denote like parts throughout the several views.'

In order that the construction, the operation. and the severaladvantages of the. Ainvention may be more fully understood andai'ipreciated, I'will now take up a detailed description thereof, inwhich I will set forth the same as comprehensively as I may.

In the drawings letter A denotes a por-- tion of a. picture frame or thelike, B denotes a sheet of paper which is pasted over the back of theframe, C denotes surplus paper which extends out over the edges of saidframe, D denotes the surplus paper which has been cut from the sheet Bby my tool, and E denotes a human hand as graspeconomical in use,aiidwliicli can'y ing my tool to perform the icuttingopera.-

i `'lhe Vinvention propery v,includes the body; portion `which consistsof sheet ,metalcut into substantially the form shown'. in .F-ig. 2

vandmit comprises the two side portions land 2, rand. a central portion.Formed onathe vopposite edges ofthe sides 1 and i2 are the respectivetaper portions orflanges 4 and 5,v`

Extending fromwthe outer.. (frear') ,coiner I of the side 1'1is atongue6 which forms a,

guide, as will hereinafter .bef fi'irthereX-fV plained. r Y Alsoextending out vfrom the edge of the sidel 1 isy a ltoot-117, thesamebeing located near the ysmaller-,endofftheyflange 41,?

" Extending out fromthei,forwardendfof i Extendringsfromthe. rear cornerof the side 2 is a tongue V9. i 1

Formed between ther tongue 9.and the intot-he form shown in Fig. 2, itisthen bent into vthe shapeshownin Figs. 1, 4, 5,6

and '8, as` follows: v Y f Y l i The central portion 3 is bentlongitudinally'into tubular form,l whereby -theside's l and are brought`flat together. y

'flhe flangesr 4 and 5 are' then'bent outwardly, directly oppositeto-each other, and at right-angles to their respectivefsides 1 and 2' dy ,v

The teeth 7, .8 and 11, extending from the sid-e1, are then bent overandl into cont-,ict with the face' of the i side 2, thereby securing thesides in position and preventing them from springing apart.

The tongue 6 is then bent outward, bringing it atan angle with relationto the side 1, substantially as shown in the drawings.v

The sides of the tongue 9 are then curved toward each other, in order tomake the under side of the tongue 9 rounding, as shown in Fig, 5 wherebyitr will make a smoothv contact with the edge of the frame.

The forward outer corners of the sides '1,

and 2v are then bent outward, opposite lto eachother, forming the wings12 and 13, bending them on the respective dotted lines y and e.

Said member 14 is adapted to slide over the smaller ends of the flanges4 and 5, and as the member 14 is forced toward the larger ends of saidflanges it is evident that the sides 1 and 2 will be securely clampedtogether.

Letter G denotes a cutting blade, which is placed between the sides 1and 2, with a portion of the edge of said blade exposed in the notch 10,as shown inFig. 5. Said blade can be removed or replaced by simplyremoving the member 14 to release the lower edges of the sides vbetweenwhich said blade is disposed.

The stem, shown alone in Fig. 3, com-l prises a straight central portion15, which is round in cross-section, and 1t 1s of such size as to fitsnugly in the tubular central portion 3. One end of the stem terminatesin a sharp point 16, while its other end Y terminates in a ring 17Vwhich forms a handle.

In Vpractice the glass,vpicture, and stiff backing is first secured inthe frame A in the usual manner. A sheet of paper is then pasted -overthe backing and the back of the frame, in order to exclude dust, smoke,and moisture, and this paper projects out beyond the frame,.usually atall four edges of the frame. My tool is then brought into action byresting the guide-tongue 6 on the sealed paper B, with the roundedtongue 9 -atsubstantially right angles thereto and contacting with theouter edge of the frame, thus bringing the juncture of the back of theframe and the outer edge thereof into the notch 10, and thereby bringingthe blade G into shearing Contact with the frame.

Therefore if the tool be grasped in ones handy and drawn along the edgeof the frame it will cut the paper along the edge of the frame,regardless of the contour of the frame, thereby forming a smooth andperi v feet job.

evident that what remains is the permanent part Bwhich latter extendsonly to the edges of the frame, as indicated in the foreground inFig. 1. l

In the next operation the tool is grasped in ones hand and the point 16is forced into the back of the frame to provide holes in whichscrew-eyes may be started, said screweyes being for the purpose ofsecuring the ends of a'cord, wire, or chain by Vwhich -theV herein setforth without departing from the spirit of the invention andwithou'tsacrificing any of the advantages 'thereof which are new anduseful.

Having now fully shown and described my invention, what I claim, anddesire to secure by LettersV Patent of the United States, isv A -toolcomprising a body including two sides, a tubular portion formed at thejuncture of the twov sides and adapt-ed to hold a stem removablytherein, a blade located between the two sides, a clamp for detachablysecuring the blade in position, a tongue disposed at an angle from thecorner of one of said sides, a second tongue extending'from thecorresponding corner of the other side,

said tongues being located at right-angles lto each other, there being anotch formed in the bodybetween said tongues to expoige a. portion ofsaid blade. Y l v In testimony whereof I have hereunto subscribed mynaine to this specification.
